洗茶的原因和来历

http://eat.csonline.com.cn 2007年12月24日17时19分星辰美食网

　　人们用茶壶冲泡乌龙茶时，习惯上把第一泡茶水倒掉，称之为“洗茶”。有些茶人解释这样做是因为要洗去茶叶中不干净的夹杂物如茶灰、尘埃。他们认为不“洗茶”的人，是“不讲卫生”、“不懂茶艺”。但有否想过，这样“洗茶”，连茶叶精华也在不知不觉中洗掉了？

　　其实，据学者考证，“洗茶”一词始用于北宋，原属于茶叶采制过程用语，后延伸至饮用过程中。而鲜叶从茶树上采摘下来以后经过初制、精制，其中有多道工序如做青、釜炒、揉捻、烘焙、筛拣等，不仅获得茶叶品级，而且达到卫生标准。其中偶有夹杂物如茶灰、尘埃，经注入沸水即倒掉，也迅即去除。而第一泡茶的操作，主要是进行浸泡，有利于茶叶的舒展和茶汁的浸出，使饮用者很快感觉到茶叶香味，而不是单纯为了洗去茶叶不卫生的东西。

　　第一泡茶的有效成分较多，如茶多酚、氨基酸、醚浸出物等，不但对人体健康有益，而且尽显茶的美味。根据有关实验，茶的香味和有益人体的成分在第一泡后3秒即开始浸出，若超过3秒钟倒掉茶水，上述茶中的有效成分就会大量损失。从市场经济角度看，为拓宽我国乌龙茶销路，谋求跨越式可持续发展，“洗茶”用语宜修正为“浸茶”或“温茶”较为确切和科学。
